WARING
DO not dismantle the housing or modify the module
Dismantling the case or modifying the module may result in electrical shock or burn.
Refer all servicing to qualified service personnel
Do not attempt to service this product yourself as opening or removing case may
expose you to dangerous voltage or other hazards.
Keep the away from liquids
Spillage into the housing may result in fire, electrical shock, or equipment damage. If
an object or liquid falls/spills into the housing, unplug the module immediately. Have
the module checked by a qualified service engineer before using it again.
Do not touch the powered DFS1000R and DFS1000T at the same time.
This module is designed for long distance connection, so the DFS1000R and
DFS1000T are isolated electrically. Touching the powered transmitter and powered
receiver at the same time may result in electrical sock.
Do not touch the module with wet hands
Touching the housing and plug with wet hands is dangerous and can cause electrical shock.

Safety and EMI
Operation is subject to the following two conditions:
(1) This device may not cause interference, and
(2) This device must accept any interference, including interference that may
cause undesired operation of the device.
NOTE: This equipment has been tested and found to comply with the limits for a
Class B digital device, pursuant to Part 15 of the FCC Rules. These limits are
designed to provide reasonable protection against harmful interference in a
residential installation. This equipment generates uses and can radiate radio
frequency energy and, if not installed and used in accordance with the instructions,
may cause harmful interference to radio communications. However, there is no
guarantee that interference will not occur in a particular installation. If this equipment
does cause harmful interference to radio or television reception, which can be
determined by turning the equipment off and on, the user is encouraged to try to
correct the interference by one or more of the following measures:
Reorient or relocate the receiving antenna.
Increase the separation between the equipment and receiver.
Connect the equipment into an outlet on a circuit different from that to which
the receiver is connected.
Consult the dealer or an experienced radio/TV techn ician for help.
CAUTION: Changes or modifications not expressly approved by the party
responsible for compliance could void the user's authority to operate the equipment.

Chapter 1 Introduction
1.1 About This Manual
This manual is part of basic Model guide reference documents that provides
information necessary to incorporate the FMextender™ DFS1000 series digital audio
interface FM transmitter and receiver for high speed data transmission interface
controller system. And this document covers spec of the FMextender.
The manual will be updated periodically to include latest component
revisions and respective specification changes. Please contact OptiPlus to obtain
information on how to support all of OPI’s optical display interface.
1.2 Introduction
The FMextender
TM
audio converter and FM transmitter are FM radio
transmitter communication interface for audio applications. The interface extends
the base technology of SPDIF audio and FM radio to provide a specification more
useful for audio applications.

Chapter 2 Audio converter system Descriptions
2.1 Feature Summary
The DFS1000R System is a complete analog-to-digital converter for
digital audio systems. It performs sampling, analog to digital conversion, and anti-
alias filtering, generating 24-bit values for both left and right inputs in serial form at
sample rates up to 200 kHz per channel.
The DFS1000R System uses a 5th-order, multi-bit Delta-Sigma modulator followed
by digital filtering and decimation, which removes the need for an external anti-alias
filter. The DFS1000R is ideal for audio systems requiring wide dynamic range,
negligible distortion and low noise, such as set-top boxes, DVD-karaoke players,
DVD recorders, A/V receivers, and automotive applications.

The DFS100T System is converter for FM Broadcasting.
This system is a receives and decodes one of 1 stereo pairs of digital audio
data according to the IEC60958, S/PDIF, EIAJ CP1201, or AES3 interface
standards. The DFS100T System has serial digital audio input port and
comprehensive control ability through a selectable control port in Hardware
Mode.
A low-jitter clock recovery mechanism yields a very clean recovered clock
from the incoming AES3 stream.
Stand-alone operation allows systems with no microcontroller to operate the
DFS100T System with dedicated output port for FM Broadcasting.
